MOCK MEAT... IT'S WHAT'S FOR DINNER... (really?, why?)

Just reading through the thread re: Anthony Bourdain. And saw some vegan and vegetarian SE's saying how good the "mock/faux" meats are, even in one case saying how they are better than the real thing.

What about you folks... is Tofurkey gonna be on your dinner table tonight? What are your favorite "mock" meats and what is it you like about them? I'm thinking of doing a taste test and then writing on my results, using a few of my vegan/ vegetarian friends as guinea pigs...
